New research progress on 613-33-2 in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 613-33-2, Name is 4,4′-Dimethyldiphenyl, formurla is C14H14. In a document, author is Brooker, S, introducing its new discovery. Formula: https://www.ambeed.com/products/613-33-2.html.
A modified preparation of the masked thiolate head unit S-(2,6-diformyl-4-methylphenyl) dimethylthiocarbamate 6 is detailed and two new masked thiolate head units, S-(2,6-diformyl-4-tert-butylphenyl) dimethylthiocarbamate 7 and S-(2-formylphenyl) dimethylthiocarbamate 8, are prepared by this method. The synthesis, crystal structure, NMR spectra and electrochemical properties of the first macrocyclic complex to be derived from 7, [Ni(2)L1](ClO4)(2), are discussed. Oxidation of [Ni(2)L2](CF3SO3)(2) (L2(2-) is derived from 6 and 1,3-diaminopropane) with cerium(IV) ammonium nitrate led to the precipitation of the black complex [Ni(2)L2][Ce(NO3)(6)], which is believed to contain a single nickel(III) centre. This complex decomposes in DMF over time (approximate to 24 hours) to form the red dinickel(II) complex [Ni(2)L2](NO3)(2). 2DMF which has been structurally characterised. Oxidation of [Ni(2)L3](CF3SO3)(2) (L3(2-) is derived from 6 and 1,4-diaminobutane) with I-2 results in ligand oxidation forming the metal free macrocycle (L3′)(2+) which contains two five membered isothiazole rings. This is confirmed by the X-ray crystal structure determinations of (L3′)(I-3)(2) and (L3′)(I)(2)(I-2)(5).
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield. If you are hungry for even more, make sure to check my other article about 613-33-2, Formula: https://www.ambeed.com/products/613-33-2.html.
